Pesticides linked to ADHD

Organophosphate pesticides act by disrupting neurotransmitters, particularly acetylcholine, which plays an important role in sustaining attention and short-term memory.

“Given that these compounds are designed to attack the nervous system of organisms, there is reason to be cautious, especially in situations where exposure may coincide with critical periods of fetal and child development,” said he study's lead author Amy Marks.

Earlier this year, a different study by researchers at Harvard University associated greater exposure to organophosphate pesticides in school aged children with higher rates of attention deficit hyperactivity disorder (ADHD) symptoms.

“These studies provide a growing body of evidence that organophosphate pesticide exposure can impact human neurodevelopment, particularly among children. We were especially interested in prenatal exposure because that is the period when a baby's nervous system is developing the most,” said Eskenazi.

More than 300 children were tested and the researchers were continuing to follow the children as they get older and expect to present more results in the years to come. The current findings were published in the journal Environmental Health Perspectives.

Mediterranean Diet Increases Fertility

Before treatment, the couple completed detailed questionnaires on their eating habits over the past month. When the researchers analysed the data, they identified two common diet patterns among the women. 1). The Mediterranean diet – defined as high in vegetables, vegetable bits, fish and beans, but low in snack foods and 2). The health conscious diet – which is high in fruits, vegetables, whole grains, beans and fish, and low in meat and snack foods.

The researchers found there was no link between the health-conscious diet and rates of pregnancy. But, the group that most closely adhered to the Mediterranean diet was more likely to become pregnant. The researchers did not assess pregnancy outcome, so the diet's relationship to the ultimate success of fertility treatment is not clear.

The Mediterranean and health-conscious diets had many similarities, but there are a few potential reasons why the former may affect fertility treatment success said the researchers.

One is the high intake of vegetable oils in the Mediterranean diet. Researchers noted that the Omega-6 fatty acids in these oils are the precursors to hormone-like substances in the body called prostaglandins. Prostaglandins, in turn, are involved in the menstrual cycle, ovulation and pregnancy maintenance.

In addition, the study found that women who most closely followed the diet Mediterranean way had higher levels of vitamin B6. One previous study found giving vitamin B to women who were having difficulty getting pregnant increased their chances of conception.

Still, diet is part of a person's overall lifestyle and the study could not account for all of the factors that could clarify the connection between the natural ways to Increase fertility Mediterranean diet and pregnancy rates
